    Write a 1-page lab report using the following scientific method sections:

    • Purpose

    o State the purpose of the lab.

    The purpose of the lab is to find out what happen if a species within a population were suddenly split into 2 groups by an earthquake creating a physical barrier like a canyon.

    • Introduction
    In biology, a species is defined as a group of organisms that are able to interbreed to produce fertile and viable offspring under natural conditions. For example, different breeds of mice are able to produce fertile and viable offspring because they are all the same species. However, bears and mice are unable to interbreed because they are two different species. If there is a physical barrier that separate a populations of species into two populations, then natural selection will cause different selective and adaptive pressures to occur between the two divided populations, and they will evolve ...

    Solution Summary

    In biology, a species is defined as a group of organisms that are able to interbreed to produce fertile and viable offspring under natural conditions. For example, different breeds of mice are able to produce fertile and viable offspring because they are all the same species. However, bears and mice are unable to interbreed because they are two different species. If there is a physical barrier that separate a populations of species into two populations, then natural selection will cause different selective and adaptive pressures to occur between the two divided populations, and they will evolve differently. This is the result of speciation in which there is a creation of two new species because of reproductive isolation.
